How to fix water damage on iPhone 5S?

Today when I came back from my pilates lesson, i was walking to the shops, then I went to get my water from my polar gear bag I noticed my bag was wet (leakage from my water bottle) my phone's case was a bit wet. When I took my phone out, tonight I dried it up with a towel, used a hairdryer, I also saw some splurges on my iphone screen, when I turned my phone, I can't use the fingerprint ID for some reason! Now I'm trying to charge my phone but it kept showing low battery and charge the phone sign, so my iPhone can't charge either. I took out the simcard and placed it back in its place, don't hve a screwdriver to remove the back of the phone, I've never used uncooked rice in a sandwich bag for my phone yet, or silica gels. I've also shaken the phone tonight to get rid of any excess water, now I've placed my phone in an empty sandwich bag and placed it inside my chest of drawers, please help? Can someone give me any solutions on how to fix water damage? How long will water damage dry up?

IPhone X camera not working?

Both cameras on my iPhone X only show black. I have quit the camera app, restarted my phone, reset all my phone settings, and updated the latest iOS. The second I open the camera app, after turning my phone back on it works, and I can use it fine, but as soon as I try again, it's back to black. I would really appreciate any suggestions on what's wrong/how to fix it!

Help me choose an iPhone? Get a 7 or 8 and wait for 2020 for a huge upgrade?

Hi y'all I'm entering college soon and I need to get a new phone. Currently I have an iPhone 6s with a home button that doesn't work, a camera that barley works, and a screen that's starting to pop off. Finally time for an upgrade. With the introduction of the new iPhone I kind of want to upgrade. Everyone says it's not worth the upgrade from the ten to the new but it would be a huge upgrade from my 6s. However there's supposedly a huge redesign coming in 2020. So my question is should I just get like a cheap 7 or 8 and wait a year to get the complete redesign or just get the new one?
